BUFFER.

Specification of Letters'latent. P t t d A 13' 1920 Application filed January 2, 1920. Serial No. 348,733.

To all whom it may concern:

Be it known that we, SENECA G. LEWIs and GEORGE W. DAUM, residing at Greensburg and Jeannette, respectively, in the county of Westmoreland and State of Pennsylvania, both citizens of the United States, have invented or discovered a certain new and useful Improvement in Buffers, of which improvement the following is a specification. 7

Our. invention consists in abuffer, capable of ready-application to and removal from'a door, and when applied preventing the door from slamming. It is applicable by hand, may be carried by the door when not in use, and is particularly serviceable when applied, to hospital doors and doors of sick-rooms, and generally, wherever noise is to be avoided, in spite of much coming and going.

The buffer of my invention is illustrated in the accompanying drawings, and a glance at them will make plain the invention, without labored description.

shows in plain the buffer made in prefe red manner; Fi II is a view. in perspec ive,

and to 'sma ler .scale, showing the buffer applied to .a door.

In preferred form the buffer is cut from a sheet of rubber suitably compounded to meet the conditions of service herein described, and consists of a medial web 1, and

of end loops 2, adapted to be stretched over the opposite knobs of an ordinary door and wherf in place to encircle the shanks on which the knobs are mounted. The length is such as to the edge of t e door and to take its position, as shown in Fi II with its opposite if}? engaging the s anks of the .opposite The requirements are, first, that the body of the bu:lfe rthe portion which abuts against the jamb when the door is swungrial, continuous throughout.

Figure I ermit the buffer to fold over shall be sound-deadening; this is accomplished in the use of a material that is in appreciable degree soft and yielding. The

further requirement is that the loops shall I rial is not otherwise important: the article may be made in part of one material and in part of another; it may be made of simple or: of compound or built-up material; or it may be made of homogeneous mate- As I have said, it is preferably made of sheet rubber, and of about an eighth of an inch or three sixteenths of an inch in thickness, though manifestly the thickness may be much greater or it may be less. v

The buffer so applied will abut, when the door is swung, against the jamb,.and

prevent slamming.

When the door is to be latched, the buffer may be freed at one end from the knob, and.

then it will hang idly from the oppositeknob, where it is out of the way, and yet ready for application at any time. Of course itmay be entirely removed when desired.

We claim as our invention;

, A door bufl'er formed of sheet rubber,

and comprising a medial web, adapted to I fold over the edge of a door, and of termi nal loops, adapted to be stretched over the opposite knobs of a door and to come to place about the shanks which carry said knobs, substantially as described.

In testimony whereof we have hereunto NEILIE KoEREEL, A..D- W Y, J

set our hands.
